How a Cool Gas Generator works
A Cool Gas Generator stores gas as a solid. When you need it, a self-sustaining chemical reaction releases nearly pure gas at ambient temperature. No pressure vessel, no leaks, no maintenance.
From solid charge to cool gas
Ignition
A small squib or electrical glow plug ignites the porous solid charge, called the CGG grain.
Reaction front
The reaction front moves through the grain by itself. Once ignited, it keeps going without any outside energy.
Self-cooling
The hot gas flows through the part of the grain that has not reacted yet, which cools it down to ambient temperature.
Filtration
For the last part of the charge a multipurpose filter takes over the cooling and filters out any volatiles.
Clean gas out
Nearly pure gas leaves the generator, ready to inflate, pressurise or breathe.
Gas storage without the drawbacks
No pressure
The gas is stored as a solid, so there is no pressure vessel to inspect or certify.
No leakage
Nothing can escape until the generator is activated, even after years of storage.
No maintenance
Install it and forget it. Generators have a very long shelf life, also in harsh environments.
Safe to transport
Several Cool Gas Generators are classified outside the pyrotechnic class, so they ship easily.
One technology, three gases
By changing the ingredients of the solid propellant we change the chemical reaction, and with it the gas that is produced.
CO₂
Inflation of booms, drag sails and heat shields, and pressurisation of propellant tanks.
O₂
Emergency oxygen for medical use, from the front line to first responders.
H₂
Hydrogen on demand, for example for fuel cells and drone propulsion.
